nscroll-position

Arguments:
stream position

Returns position after modifying it to be the position to which stream
has been scrolled relative to the page top left. This is the
destructive version of scroll-position.

An application may override the default method of this and several
other generic functions in order to implement a custom scrolling
scheme that scrolls by logical picture objects rather than by
pixels. See the source code of the example entitled 'Scrolling by
arbitrary objects rather than pixels' in the Examples tab of the
Navigator
dialog for a complete example. More on this point and a list of the
relevant generic functions can be found on the horizontal-scroll-bar and vertical-scroll-bar
pages.
